$update = mysql_query("UPDATE resume SET name='{$_POST['name']}', age='{$_POST['age']}', sex='{$_POST['sex']}', mobile='{$_POST['mobile']}' WHERE id={$_POST['id']}");

It is dangerous to insert $_POST'ed values without checking.

$update = mysql_query("UPDATE resume SET name='{$_POST['name']}', age='{$_POST['age']}', sex='{$_POST['sex']}', mobile='{$_POST['mobile']}' WHERE id={$_POST['id']}") or die(mysql_error());

Post the error that will show.

$sql = "UPDATE resume SET name='{$_POST['name']}', age='{$_POST['age']}', sex='{$_POST['sex']}', mobile='{$_POST['mobile']}' WHERE id={$_POST['id']}";
$update = mysql_query($sql) or die(mysql_error() . '<br/>' . $sql);

Try again, and paste the query too.

try this - if something goes wrong u can still go forward - 1st try to connect and keep the rest of the code indented .

$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
echo "Connected to MySQL<br>"

$selected = mysql_select_db("examples",$dbhandle)
or die("Could not select examples");

Instead of putting the SQL Statement in the mysql_query() function, put it into a variable and echo out that string so you can see the actual SQL statement that is being passed.

$sqlStmt = "UPDATE resume SET name='{$_POST['name']}', age='{$_POST['age']}', sex='{$_POST['sex']}', mobile='{$_POST['mobile']}' WHERE id={$_POST['id']}";
echo $sqlStmt;
mysql_query(sqlStmt);

If you cannot see the statement on the web page, do a View Source and you should be able to see the SQL statement somewhere in the HTML source.

First check your posted values by using the following statement.
print_r($_POST);

If posted values are OK, then execute the query in the following manner.

$update = mysql_query("UPDATE resume SET name='$_POST[name]', age='$_POST[age]', sex='$_POST[sex]', mobile='$_POST[mobile]' WHERE id='$_POST[id]' ");
